7 Claims.

This invention relates to firearms having short stocks or pistol gripbutts, in combination with a light Wire folding stock for extension toshoulder rest firing. Objects of the invention include the provision ofa light weight, short firearm having a folding stock, such firearm beingparticularly adapted to the needs and uses of parachute troops, tank.motorcycle, and other mechanized troops, police riot squads, and otherpersons needing an effective weapon of light weight, easy manipulation,and smallsize but of greater effect and accuracy than the usual handgun.

Other objects of the invention include the provision of a sturdy,folding, light gun which can stand great abuse in warfare withoutbecoming disabled, and to this end the invention comprises a specialpistol grip and unitary long forearm forming the stock, a short barrelon the forearm, and a sturdy folding wire frame shoulder stock r butt,said wire frame being especially constructed for rigidity in use, easeof operation, and small liability of breakage even when thrown about asin parachute landings and fighting, combined with small size and lightweight for great convenience.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. 1 is aview in side elevation of a firearm according to the invention andshowing the shoulder stock in folded condition;

Fig, 2 is a view similar to Fig. 1 but with parts broken away andshowing the shoulder stock. in

extended condition;

Fig. 3 is a rear view of the pistol grip looking in the direction ofarrow 3 in Fig. 1;

Fig. 4 is a section on line 4-4 of Fig. 1;

Fig. 5 is a plan view of the shoulder stock bearing and catch plate;

Fig. 6 is a section on line 6-6 of Fig. 5;

Fig. 7 is a plan view of the cover plate for the bearing and catchplate; and

Fig. 8 is a section on line 88 of Fig. 1.

In Fig. 1, the numeral l0 indicates a barrel having a receiver l2 formechanism providing for semi or full automatic fire of shells housed ina magazine l4, depending from a magazine guide l6 and being quicklydetachable therefrom for'inbe made of wood or similar material anddepending from its rear end it is provided with a unitary pistol grip20. Means not shown may be used to secure the parts together, and as sofar described the firearm may be used as a hand gun by grasping thepistol grip in the gun hand, or it may be used as a two-hand gun, forinstance in firing from hip or waist level, by grasping the grip 29 inthe gun hand and using the depending 7 magazine I4 as a fore grip in theother hand. Sling swivels 22 may be used for a sling and to strap theweapon to the thigh for ease in carrying, as for instance by parachutetroops, motorcycle troops, police, etc. It is preferred to make theoverall length of the weapon as so far described about twenty-two inchesfor easy carrying on the thigh or elsewhere, but this length is notnecessary and, may be varied without de arting from the scope of theinvention.

A plate 24 having a transverse lug 26 in the plane of the plate isimbedded in the stock so that its outer surface coincides with thesurface of the stock. as shown in Fig. 4. A pair of strong spring ears28 extend outwardly from plate 24, these ears having their free endsbent slightly toward each other, Fig. 6, and they are provided withdepressions 30 for a purpose to be described. A pair of spaced fastenerreceiving apertures 32 extend through plate 24.

A cover plate 34 corresponding largely in shape to plate 24 overlies thelatter and is secured to the stock by fasteners 36 extendingtherethrough and through apertures 32 in plate 24, Plate 34 is providedwith a transverse generally semi-cylindrical depression 38 intermediateits ends, and as shown in Fig. 4, this depression, together with theadjoining part of plate 24, forms a journal for a wire 40, the latterbeing part of an open Wire shoulder stock or butt 42 which clearly ispivotable from Fig. 1 to .Fig. 2 positions to be folded against theforearm 18 or to extend rearwardly for use as a shoulder stock. Plate 24takes most of the Wear of the pivoting action and ensures againstloosening of the wire stock. The inwardly turned ends of ears 28 act toguide the runs 44, 46 onto the ears, and depressions 30 snap-lock theseruns rigidly in extended position of the wire stock. The lug 26 acts asa stop and bearing plate for the wire frame run 44 in extended positionof the wire stock so as not to wear the forearm and consequently losethe rigidity of the stock after use. Also, by the two plateconstruction, the wire 40 is enabled to pivot right at the surface levelof the forearm l8, and ears 26 hold the wire stock at this the rear endof the receiver. This forearm may level, so that the stock is enabled tolie just about in contact with the forearm and pistol grip and as closethereto as possible for easier and more accurate manipulation of thegun.

It is to be noted that plates 24, 34 are set at an angle to the barrelso that the wire stock will, when extended, also lie at an angle to thebarrel in the natural position for a shoulder resti stock. However, whenfolded, the run 44 would extend above the barrel and might interferewith effective use of the weapon if operated in folded condition. Tolocate the wire stock as shown in Fig. 1, a catch plate 48 is sunk intothe forearm as shown in Fig. 8, and an car 50 integral with the catchplate is located at an angle to the shoulder member 52 of the wirestock. Hence the latter cannot be secured by catch ear 50 withoutdepressing the entire wire stock in the 4. A firearm as recited in claim1 wherein said first named plate lies substantially flush with thesurface of the forearm, and including a lateral extension on said firstnamed plate against which the folding shoulder stock may be stopped inits extended condition.

5. In a firearm of the class described, a barrel, a forearm supportingthe barrel substantially throughout the length of the barrel, a pistolgrip at one end of the forearm, and a folding shoulder stock mounted onsaid forearm, said stock having a wire portion acting as a pintle, apair of superimposed plates on said forearm, means forming an outwardlyextending recess in one direction of arrow A in Fig. l, and the loweredge of ear 50 will then hold the stock as shown, providing a corner 54for conveniently hanging the Weapon on a hook or rack.

It will be seen from the above that I have provided a light, easilymanipulatable weapon having a light, but sturdy and convenient shoulderstock, the gun being usable as a shoulder or hand gun and being easilycarried and stored in tanks, planes, cycles, etc.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what I claim is:

l. A firearm comprising a forearm having a pistol grip, a foldingshoulder stock, means mounting the folding shoulder stock on saidforearm, said means comprising a, plate in said forearm, a "pair ofspring ears extending outwardly of the forearm, a second plate overlyingthe first named plate, a depression in the second plate forming ajournal with a portion of the first named plate, a portion of saidshoulder stock being pivotally disposed in said journal, and otherportions of said shoulder stock being adapted to be latched by saidspring ears in extended condition of the shoulder stock.

2. A firearm as recited in claim 1 wherein said first named plate hasits outer surface substantially flush with the surface of the forearmand said second plate has its inner surface substantially flush withsaid forearm surface.

3. A firearm as recited in claim 1 wherein said second plate liesbetween said ears in contacting relation therewith.

of "said plates, said pintle being journaled in said recess and incontact with the other plate, a pair of spring ears on one of saidplates for latching the stock in shoulder-rest condition, and a springcatch for latching the stock in folded condition thereof.

6.- A firearm as recited in claim 5 including a lateral lug on. one ofsaid :plates, said lug extending laterally beyond both plates and beinglocated rearwardly of said pintle to act as a stop for the foldingshoulder stock in extended condition thereof.

7. In a firearm of the class described, a short barrel and receiver, aforearm substantially the length of the barrel and receiver, a, pistolgrip at one end of the forearm, a bent wire shoulder stock pivoted tothe forearm to be swung between positions wherein the stock lies infolded condition against the forearm or selectively extends rearwardlybeyond the pistol grip to form a shoulder rest, and means pivoting thestock to the forearm, said means comprising a pair of superimposedcontacting plates one of which lies fiush with the surface of theforearm, said one plate having a pair of outstanding spaced spring ears,the other plate lying between the ears and forming a, lateral supporttherefor, a lateral stud in said one plate to act as a shoulder stockabutment, and an outwardly extending substantially semi-cylindricaldepression in said other plate forming :a journal with the adjacentsurface of said one plate, a portion of said shoulder stock enteringsaid journal, and said stock having means adapted to be latched by saidspring ears in one position of the stock.
